HSBH Algorithm Based on Chaotic Map

LSB is a classical algorithm of information hiding in the spatial domain. Although it has high capacity of information hiding, the robustness is weakening. Considering the robustness and security of information hiding, a new spatial domain image information hiding algorithm (HSBH) is proposed, the algorithm improves robust and security by interval set and chaos located. Experimental results indicate that the algorithm can extract the whole secret information from the camouflage-image which was overlapped random noise. When r=4, the value of gray is 46.9% of the total value of gray.
